Freeze Dryer


Model: Freezone

Manufacturer: LabConco


Freeze drying has been used in a number of applications for many years, most commonly in the food and pharmaceutical industries. There are, however, many other uses for the process including heat-sensitive samples preparation, plant material research, the stabilization of living materials such as microbial cultures, long term storage of HPLC samples, preservation of whole animal specimens for museum display, restoration of books and other items damaged by water, and the concentration and recovery of reaction products.

Freeze drying involves the removal of water or other solvent from a frozen product by a process called sublimation. Sublimation occurs when a frozen liquid goes directly to the gaseous state without passing through the liquid phase. In contrast, drying at ambient temperatures from the liquid phase usually results in changes in the product, and may be suitable only for some materials. However, in freeze drying, the material does not go through the liquid phase, and it allows the preparation of a stable product that is easy to use and aesthetic in appearance.
